SAFETY-RAZOR.

Specification of Letters Patent.

Patented May 9, 1911.

Application filed January 11, 1909. Serial No. 471,802.

To all whom it may concern:

Be it known that I, FLOYD D. JONES, a citizen of the United States,residing at Kansas City, in the county of Jackson and Stateof Missouri,have invented certain new and useful Improvements in Safety-Razors, ofwhich the following is a specification.

This invention relates to safety razors, and my object is to produce adevice of this character having a universally-adjustable handle toenable the operator to closely shave any part of his face without dangerof cutting a contiguous part.

A further object is to produce a safety razor equipped with a blade ofstandard type in'cross-section, that is a blade corresponding to that ofan ordinary razor though it may vary therefrom in size.

A further object is to produce a razor having a guard for reliablyclamping the blade in the sheath or holder and incapable of oscillatorymovement. A still further object is to produce a guard provided withlugs overlapping the ends of the cutting edge of the blade to render itimpossible for either corner of the latter to scratch or cut the face ofthe operator.

Another object is to produce a safetyrazor of simple, strong, durableand inexpensive construction.

With these objects in view and others as hereinafter appear, theinvention consists in certain novel and peculiar features ofconstruction and organization as hereinafter described and claimed; andin order that it may be fully understood reference is to be had to theaccompanying drawing, in which- I Figure 1, is a central verticalsection of a safety razor embodying my invent-ion, on a magnified scale.Fig. 2, is a section on the line IIII of Fig. 1. Fig. 3, is a plan viewof the razor. IVIV bf Fig. 1. Fig. 5, is a front view of the lowerportion of the blade and guard to disclose one of the lugs of the guardto protect the face from being cut or scratched by the adjacent cornersof the blade.

Referring now to the drawing in detail, in which like referencecharacters indicate corresponding parts, 1 indicates a razor blade ofthe usual hollow-ground type, the blade being of suitable length and inother respects substantially the same as the cutting portion of anordinary razor blade.

2 indicates a holder or sheath comprising Flg. 4, is a section on line ia top portion 3 and downwardly conver ing walls 1 and 5, said walls'bcing curve by preference to correspond substantially to the hollowsides of the blade. The wall 5 is preferably thickened or bossed at itscenter as at 6, and is provided with a threaded passage 7 and atopposite sides of said boss 6 it is rovid'ed with a pair of similarbosses 8, to slidingly receive the guide pins 10 pro- 'Jectmgrear'wardly from the, guard 9, which fits within the holder or sheathagainst the rear side of the blade and corresponds approximately incurvature to said blade and the rear wall of the holder or sheath.

By preference that portion of the guard below the holder or sheath isspaced slightly from the blade, and at its lower margin said guarddiverges slightly with respect to and depends below the cutting edge ofthe blade, the said depending portion being in the form of a pluralityof teeth 11, and in order to guard against any possibility of the cornerof the blade cutting ones face, said guard is provided at its ends withsmall lugs 12 fitting squarely against the rear face of the bladecoincidental with its sharp corners.

13 is a clamping-screw mounted in the threaded opening of the boss 6 andclamping the guard firmly against the blade 1 and the latter reliably inposition, the guide pins and bosses serving to guard against anytwisting movement of the guard so as to compel the same to engage theblade in a pro er and most effective manner for holding tlie sameagainst slippage, it being noted in this connection that thecross-sectional form of the blade and its holder or sheath preventsdownward movement of the blade.

The head of the clamping screw is peripherally toothed as at 14 androtatably secured upon the projecting portion 15 thereof is a bracket16, provided with a spring-actuated pivoted catch 17, for engagementwith one of the notches of the toothed eriphery 14 to lock the bracketrigid with the clamping-screw. The .cnds of the arms of the bracket 16are semi-circular in form and one of them is notched as at 18 andconnecting said arms centrally of their curved edges is a cross pin 19which forms a pivot for the handle 20, and in order to secure the handlein the desired position or at the desired angle with respect to theblade, it is equipped with a pivoted catch 21 adapted to be held by aspring 22 in engagement with one of the notches 18, the catch 21-preferably occupying a recess 28,the spring being also thus enable theoperator to more conveniently and effectively handle the blade in theshaving operation. It will also be apparnt that the handle ,is not onlyadjustable transversely of the blade but can also be so adjusted as tobe. capable ofstanding at any esired angle from the clamping-screw, thisadjustment being effected by first tripping catch 17 and turning thebracket on the clamping-sleeve and permitting said catch to rengage theclamping-screw when the desired adjustment is attained, this rotatableadjustment of the bracket obviously determining the plane in which thehandle proper may be swung upon its pivot 19.

In assembling the blade, it is slid endwise into the holder or sheathuntil arrested by stops 5 projecting forward from one end of wall 5,such arrest giving assurance to the person in control that theclamping-screw may be screwed home to secure the blade in positionwithout danger of snapping the blade by unequal pressure, such as wouldbe applied if only one of the lugs engaged the blade.

From the above'description it will be apparent that I have produced arazor possessing the features of advantage enumerated in the statementof the object of the invention and I wish it to be understood that i donot desire to be restricted to the exact details of construction shownand described as obvious modifications will suggest themselves to oneskilled in the art. I

Having thus described the invention what I claim as new and desire tosecure by Letters-Patent is 1. A safety razor, comprising a blade, aholder receiving the blade and provided in its rear wall and at oppositesides of its renter with parallel guide holes, a guard between the bladeand the rear wall of the holder provided with rearwardly projecting pinsextending through said guide holes, means carried by the holder forclamping the guard and blade tightly together and in fixed relation tothe'holder, a bracket swiveled to' said means, means to secure thebracket against accidental swivel movement, a handle pivoted to saidbracket, and means for securing the handle at the desired point ofpivot-a1 adjustment with respect to said bracket.

'2. A safety razor, comprising a blade, a holder receiving the blade andprovided in its rear wall and at opposite sides of its center withparallel guide holes, a guard between the blade and the rear wall of theholder provided with rearwardly projecting pins extending through saidguidev holes, means carried by the holder for clamping the guard andblade tightly together and in fixed relation to the holder, a bracketswiveled to the said means, means to secure the bracket againstaccidental swivel movement, and a handle secured to said bracket.

3. A safety razor, comprising a blade, a

holder receiving the blade, a guard between the blade and the rear wallof the holder,

means for clamping the guard against the blade to secure the latterfirmly in position,

a bracket rotatably secured to the clamping means, means to secure thebracket rigidly to the clamping means, a handle pivoted to the bracket,and means for securing the handle at any desired point in its pivotaladjustment.

4. A safety razor, comprising a blade, a holder receiving the blade, aguard between the blade'and the rear wall of the holder,-aclamping-screw carried by the holder to clamp the guard firmly againstthe blade and the latter securely in position and provided with anotched head, a bracket rotatably carried by the clamping screw andprovided with a catch engaging said notched head, said bracket havingparallel arms rounded at their rear ends and one of them "notched atsaid end, a pivot pin carried by said bracket, a handle pivoted on saidpin between the arms of the bracket, and a spring-actuated catch pivotedto the handle and yieldingly engaging one of the notches in the notchedarm of the bracket.

In testimony whereof I aflix my signature, in the presence of twowitnesses.
